On 3 October your 0830 zone time DR position is LAT 26°15.0'S, LONG 73°16.0'E. Your vessel is on course 280°T at a speed of 19.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option A — 1201

Calculating local apparent noon requires determining the Greenwich Hour Angle (GHA) of the Sun combined with the vessel's estimated longitude at the time of transit. Account for vessel speed and course vector changes using standard Bowditch sight reduction procedures.
